Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as electrolytic capacitors, use aluminum as the anode, the anode oxide film as the dielectric, and the liquid electrolyte as the cathode. They have the characteristics of large capacitance, small volume, light weight and low price. So, they are widely used in AC and DC power supplies and various electronic devices, especially suitable for high-frequency circuits.

USR1A220MDD application field and working principle

USR1A220MDD is an aluminum electrolytic capacitor. The main areas of application include computers, wind turbines, household appliances, communication equipment, mobile phones, video equipment, etc., as well as LED lighting, solar energy inverters, electric vehicles, etc.

The working principle of USR1A220MDD aluminum electrolytic capacitors is that when the power is switched on, a large amount of electricity is often produced, which can damage the electrical equipment. At this time, the aluminum electrolytic capacitor will act as an instantaneous flow guide to make the instantaneous current flow within the device, reduce the impact voltage, and protect the safety of the electrical equipment. The aluminum electrolytic capacitor also helps to filter the current inside the device, eliminating interference, residual current, and enhancing the output stability of the device.

Advantages and Disadvantages of USR1A220MDD

The advantages of USR1A220MDD aluminum electrolytic capacitor include: capacitance is large, volume is small, and cost is low. It can be used in any environment, its performance is reliable, and its vibration proof ability is strong.

However, it also has some limitations. The pure aluminum canister is easily corroded in humid environments. The service life of the aluminum electrolytic capacitor is related to the temperature of the working environment. USR1A220MDD is not suitable for environments with high temperature and high humidity. In addition, the capacity of the aluminum electrolytic capacitor decreases as the temperature increases and its stability is not as good as the specialty capacitor.

Conclusion

USR1A220MDD aluminum electrolytic capacitors have the advantages of large capacitance, small volume, and low cost, so they are widely used in various electronic devices. However, since it is easy to be corroded in humid environments, it is not suitable for high temperature and high humidity, its capacity is reduced as the temperature increases, and its stability is not as good as that of the specialty capacitor.
